No More Blown Headgaskets! No matter what your pleasure... Supercharger, Turbo, Nitrous, or Stroker - these Cometic MLS (Multi-Layer Steel) Head Gaskets will keep the lid on things. Made from 3 layers of Stainless Steel and specially embossed around each water and air passageway, our head gaskets will survive where no others will.
Adjustable: The gaskets can be ordered with several different center-section widths - so you can vary your compression ratio or give yourself a little more valve clearance for hi-lift cams. .045" is standard - but the thickness of the gasket can be special ordered all the way up to .120" if needed for your application.
